What started out as simply a question of whether or not they could… [G2AS] decided to try making a laser cut serrated bread knife — out of plastic.
Now from a distance this may look like they just took their laser cutter and cut out the pattern of a knife, with a jigsaw edge. But no, they actually laser cut a jig which allowed them to cut the serrated edge on an angle, creating an actual sharp edge. It’s quite the setup, but a pretty awesome result.
From just wondering if they could or not, they moved on to develop it as a simple product to share with the world — they’ve posted all the design files and instructions on how to make your own!
It’s really quite amazing all the things you can do with a laser cutter. You can build just about anything using a laser cutter and Delrin sheets — you can etch color into parts with a simple technique, and how about using laser cutting as rapid manufacturing of folded acrylic parts?
